RADIATOR.

Application tiled March 27, 1926. Serial No. 97,860.

This invention pertains to radiator construction and more particularly to the construction of a section for radiators that are directly fired; that is, forthat type of radi? ator which is adapted to replaceuthe ordinary radiator in a steam or hot water heating system orto be 4operated independently or ex clusively of such system. The general character and uses of l:ii-radiator of this t'ype, to thesections or loops of which my ntion may be applied is illustrated and desc i ed in Patent #1,342,509 dated .Iune 8, 192i) and in my prior Patent No. 1,580,651, dated April 13, 1926, both of which are=` assigned to the assignee of the present application.

The radiator. to whiclithe present form of my invent-ion isapplied is primarily adapted to be heated. by gaseous fuel and lis not equipped with the usual connections for delivering the heated-products of combustion into a chimney', iuerorstacl; after use. In-

stead, the heated productsvof combustion are v preferably used to initiate the heating of .the room oi' tlielike in which the radiator is situated and thereafterto supplement the beatF ing effect of the steamgenerated or the vwater heated in the, radiator, onsuch room. Maximum etiieiency is thus secured,

However, it has been found that with rad ia tors so constructed certain difficult-ies and objectionable features are encountered. When,

for instance, suchV radiator be placed beneath and adjacent a window, the heated gases are .apt to Scorch, if not set fire to thel window curtains or drapings. Sometimes a. quantity of fuel gas is permitted to escape before a match is applied to the burner to ignite it. The unburned fuel gas rises upwardly between the radiator sections or loops and when anatteinpt. is made to ignite thefuel gas atthe burne rv,. tlie flame followsthe same upward path ii'iiting the gaseous fuel which has risen above the sections. The danger is apparent if lilmy curtains or drapes overhang the radiator.

But the housewife is also concerned about the. dirt and soot which drops from the burner chamber of the present type of gas-fired radiator onto the ioor or carpet beneath the radi. ator. This often happens-because it has been considered necessary for numerous reasons to place the. openings for admission of air to the burners to support combustion, directly and centrally fore and aft beneath the radiator, and. as some soot forn'is-above theburner and drops therefrom from.A time to time,-it follows thatsuch soot and dirt Vfalls upon-the' Hoor."

With my invention the objectionablefea-v tures above. enumerated and others are entirely obviated.. A'ny unburned' gases andthe heated gases rising from tlie'burnei' p'ass be- A'tween the severalsections of the'radiator andare deflected forwardlyinto the room andprevented fromrising immediately and directly upward where they might det'i-iii'ientzilly affeet objects suspended over the radiator. The

noA

radiator sections are also so arranged and co'nstructed that anysoot and'dirtzwhicli mayin the course of time, accuiiiulate-Within the'conibustion chamber or above it, may :not -all v f will in this-connection be noted that the heating effect of a radiator bui-lt in accordance Y:, airA to with the invention will be initiated by the hot gases or products of combustion which are thrown out'into tlie-l'oo'maway from the wall.

or other place -adj aceiit ivhi'cli the.` radiatorA may be positionedand thc-.heatingt'rifect'of the water heated or thc steam generatedin the y radiator enhanced so long as the burner re` mains lighted,'all. of which contribute to quick and steady heating of the room or chamber within which the radiatorinay be located.

Many other objects and advantages'includ-- f ing the details of construction andoperation should be readily appreciated after perusal of t-he description and claims and after viewing the attached drawingsin which:

Fig. 1 is a front elevation of a radiator loop assembly, the loops being constructedin Y accordance with what is at present a preferred form of the construction.

Fig. 2 is a section taken on the line ofA Fig. 3 is a section taken on the iine 3 3 of Fig. 1. Y

Fig. 4 is a section taken on the line 4 4 of Fig. e and Y Fig. 5.is a

section taken on the line of F ig. 2.

In the drawing the radiator is' shown as composed of end sections or loops generally designated 2 and 3 each provided with legs Lland 5 for their support as well asthe support of the intermediate sections or loops generally designated 6 of which but three are shown in Fig. 1. Each section or loop, in the preferred form, is a casting cored out to provide a top header chamber 7, a bottom header chamber 8 and a plurality ofA vertical columns 9, 10, 11 and 12 connecting the topgand bottom header chambers.

ach intermediate section on both sides of the top and bottom header chambers and each end section on the side of the top and bottom headers adjacent an intermediate section (in case of two sections only, the sides of the headers of the end sections adjacent the opposite end section) are bored out, preferably with a tapered bore 13 for the reception of'a nipple 14, whereby the sections may be interconnected in water tight engagement. The bottom header terminates in a wall -15 extending transversely across the section and from end to end thereof to provide, with the wall of the shell 16 integral with the walls of the end columns 9 and 12, a combustion chamber 17 within which the gas or other fuel burner vis adapted to be situated. The lowerxnost portion of the shell 16, preferably centrally between the front and rear of. the radiator sections,v is4 cut away, as indicated at 18, for lthe admission of air to the combustion chamber 17, but since soot and dirt normally' collecting on the bottom of the wall 15 and elsewhere within the radiator drops under its own weight or after slight vibration it would, by reason of the opening provided by the cutaway portion 18 directly thercbel'ow, fall through the opening onto the floor. To overcome this and prevent the occurrence of this objectionable action, I prefer to cast a plate lor battle 19 integral with the shell 16 and over, but spaced from, the lower portion of the shell wall containing' the vent opening and with its ends 20 extending over and beyond the extreme ends of the vent opening, so :that soot or dirt falling from the wall 15 or from elsewhere in the radiator-will be caught upon the baille or plate 19 or at the ends of the wall of the shell 16 and out of the way of the vent openings. This plate also serves another purpose in that it is more desirable to have air for the support of combustion within the chamber entering at the opposite sides of the burner, not shown,

but which as is usual extends longitudinally and centrally through the combustion chamber sections, than it is to have the air entering in one column directly beneath the burner.

As has heretofore been noted, it is desired to direc-t the heated gases of combustion, Y. after they have had an opportunity to heaty the waten-l other Huid contained within the radiator and thereby expended some of their` energy, out into the room or other place in which the radiator is. located. It is also necessary that the combustion chamber be substantially `closed between the several sections of the radiator for obvious reasons.

To this end each intermediate section or loo is provided with a rib 21 on each side an each end section with such a rib on but one side. These ribs preferably extend from some point designated 22 outwardly along the bottom header 8 to a point adjacent the front edge of the section, thence downwardly across the header and following the contour of the shell 16, rise again adjacent the back edge of the radiator section, approach for a short distance toward the point 22 of the beginning of the rib and thence curve upwardly, as shown-at 23 along the column 10 to the top header nipple connection A13 where it is joined thereto, as shown -at 24. Between the points 23 and 24 each rib may have a flat -top face, but from the point 22 to the point 23 one rib 21 is cuir-away for a portion of its width -or thickness on one side, as shown at 25, while the rib on the opposite side of the section is cut away at the opposite side as shown at 26. In other words, the portions of the ribs'about the combustion chamber' section 17 are-so formed on opposite sides of the radiator section that they will interlockingly engage with the same portions of the rib of the adjacent section and thereby provide a substantially tight connection for the combustion charnber. The end sections of course, will be provided with one rib each whih will be formed to correspond to the rib of the `adjacent face of the adjacent section, while any suitable arrangement may benrade fr closing the ends ofzthe combustion chamber'in the-end sections whereby the radiator may be proV vided with a fuel burnerand pilot light etc.,

of adjacent `sections orloops cooperate together and with what vIishall term auxiliary ribs 28 to aid in directing the gases without eddies upwardly betweenvthe points 22 and 23 of the ribs 21. As the gases rise along lthe columns between and through `the Sections they effect heating of the sections and when they reach the upper portions ofv the columns the upper portions of the ribs 21 together with the nipple coupling connections 13' serve to directthem forwardly intoI the room within which the radiator is situated.' The adjacent sections in connection with'the ribs 21 and thetop header coubottom hader'with the columns open to vchange Without plings 13' provide openings giving a register effect as vshown at A, B', C and D in Fig. 1.
